Answer:
it would be -90⁰ because its clockwise its the opposite direction
Answer:
Step-by-step explanation:
If you draw a line from the origin (0,0) to L ( the original point ) and a different line from the origin to the image L' you can see the angle of rotation as being

Answer:
Alisa practiced for 240 minutes (4 hours). In total, they practiced for 288 minutes (4.8 hours).
Step-by-step explanation:
If James practiced for 48, and Alisa practiced 5 times as long, then we would multiply 48 by 5 (240 minutes).
If we want to find how many minutes in total they practiced, then we would add 240 minutes (Alisa's practice time) and 48 minutes (James' practice time) together, which would equal 288 minutes (4.8 hours).
Equation: y=48+x
The answer is 16.27 rounded to the nearest hundredth
